A, the city road network (shapefile files)
Two, taxi GPS data sets
Goal: record of taxi GPS map matching
Confusion at present: I have the way of information, but in fact these roads is the point of multiple thread together, and I use Python pyshp library after read this network file, there are multiple points of latitude and longitude, and each point ID, and so on, but these how to build the topology of the network? (as shown)
Because want to use to build a good network to GPS map matching, thus speed up the search,
Online said, the use of adjacency table stores, but the point is not the road intersection point!
And even if find a road intersection, nothing can also judge that he is the basis of a road intersection,
You, the hope can give some guidance, thank you!
